Side car

Postby biketrip » Wed Sep 05, 2012 2:08 pm



I have a california side car on my 1986 GL1200 with a woble problem, trailing arm is tight, steering is tight, tires are at 33 psi front, 40psi rear. will have side car tire balanced today. Any suggestions about lean angle of bike in relation to side care?
Thanks for any info.

I truly don't know the first thing about side cars...but...if it wobbles,I'd be looking at the tracking.
I'm guessing here,but if you could pull a line center of the bikes wheels and another from the side car wheel,the 2 should be parallel or possibly a slight toe in.
I'm sure there's some formula and adjustment for this.Its where I'd start looking if everything else is tight.

Even a well set up sidecar will cause a tank slapper at slow speeds. Most of this is caused by the rider holding the grips too tight. Try a real loose grip and I bet some of the wobble disappears. The best way to get rid of it totally is to fit Earles Forks (Leading Link Forks). These can be ugly though, so an easy fix is a steering damper. You need to mount a damper towards the rear of the wheel on one end, and to the front of the sidecar chassis on the other end. Make sure you have good clearance from lock to lock. Alternativly, a smaller damper attached to the outside of one of the fork legs, and back to a solid point of the bike. Both ways work, as long as the damper is at right angles to the movement of the attaching point on the front forks.

Cheers.

Thanks for the info. Set the toe in to 1 inch & outward lean to 1/8th inch per info from Ca. sidecar, and no more wobble at any speed.
